Scenario The process of a firm is as follows. Flow units enter at the rate of 5 units per minute. All units wait in line for Step A and then do Step A. Then about 0.65 go to wait in line for step B. When flow units finish Step B, 1 exit. About 0.35 of the units leaving Step A go to Step C. After Step C, 1 of the flow units that went through Step C goto Step D. After Step D, 1 of the flow units that went through Step D exit. On average 3 units are waiting for Step A and it takes 1.5 minutes to do Step A. On average 1 units are waiting for Step B and it takes 6 minutes to do Step B On average 4 units are waiting for Step C and it takes 3.5 minutes to do Step C On average 2 units are waiting for Step D and it takes 3 minutes to do Step D 1 Create a process flow diagram of the above scenario in the space below. Be sure to label each Activity (A, B etc) and include the buffers. Also, include the variable for Little's Law below the symbols. R= Start 2 Based on the flow diagram above, how many flow units are in the system? system 3 What is the flow time for units exiting after B?
